Another ~1 day project so we’ll keep it short and stick to the details:
Goal: Make a set of 16mm cubes to serve as the base of a dice set.
Raw stock: 3/4"x3/4"x1’ 464 brass bar
Considerations:
Brass should be lead free as these will be high touch items. I could coat the items and use free machining brass to achieve reasonably low exposure but I want to work with 464 anyway so it works out.

A lead-free alternative to 485 brass, 464 brass offers good weldability, strength, and wear resistance. It’s widely used for marine hardware, pump and propeller shafts, and rivets.
